<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level low is moving off to the east today after providing moisture to mainly the southern part of the state. The next upper trough and cold front will move in tomorrow morning bringing more moisture. Cold front will
pass through between the early afternoon and evening. Air mass will remain unstable and smoke dispersion decent under light to moderate wind flow.</div>
<div> </div>
<div> OUTLOOK (FRIDAY - SUNDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough moves through Friday as it dives to the south into California. Expect some lingering showers in the cool, unstable air mass. Snow level will be around 3500 – 4000 ft. Minor ridge builds in Saturday but
will not warm the air mass too much. Skies will remain mostly cloudy. Next stronger front and trough arrive Sunday bringing a good dose of moisture and wind. Mixing and smoke dispersion will remain good to excellent through the period.</div>
